Energy needed in breaking a drop of radius R into n identical drops of radii r is given by
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Energy needed = Increment in surface energy = (surface energy of n small drops) – (surface
energy of one big drop)
= n4 
r 2 T - 4 
R 2 T = 4 
T (nr 2 - R 2 )
